It is unclear in the pursuit vessel and the Cardassian patrol cruiser represent the same class or not. The term "patrol ship" was a Federation description for the Hideki class, whereas the term "pursuit vessel" was used by Dukat to describe something comparable to the Danube class. However, because both terms (using the term "patrol cruiser") were used in two separate references in the same episode, it might denote the possibility that these are two different vessel types.
